Sesame (Sesamum indicum L.) response to drought stress: susceptible and tolerant genotypes exhibit different physiological, biochemical, and molecular response patterns.

ABSTRACT: Drought is one of the main environmental stresses affecting the quality and quantity of sesame production worldwide. The present study was conducted to investigate the effect of drought stress and subsequent re-watering on physiological, biochemical, and molecular responses of two contrasted sesame genotypes (susceptible vs. tolerant). Results showed that plant growth, photosynthetic rate, stomatal conductance, transpiration rate, and relative water content were negatively affected in both genotypes during water deficit. Both genotypes accumulated more soluble sugars, free amino acids, and proline and exhibited an increased enzyme activity for peroxidase, catalase, superoxide dismutase, and pyruvate dehydrogenase in response to drought damages including increased lipid peroxidation and mem
